72) all whom it ma Be it known t ICKS, a citizen of to permit convenient and qulc removal of means or the brake mechanism. Another objcct is to ermit of interchangin the rear traction wheel 0 the motor cyc e for the front or steering Wheel whenever it is desired to do so.

In order to accomplish the desired result, nect one end of the hub of the rear traction v i rheel with the driving gear, and means for detachablfr connecting the other end of A practical embodiment of the invention is represented in the accompanying drawings forming a art of this specification, in which similar 0 aracters of reference indicate corresponding parts in all the views.

Figure 1 is a cross section of the demountable and "interchangeable wheel in position on the motor cycle, the section being on the line l.-1 of Fig. 2;

Fig. 2 is a sectional side elevation of the same on the line 2-2 of Fig. 1;

Fig. 3 is a sectional plan view of the same on the line 8-3 of Fi 2; and

Fig. 4 is a perspictllve view of the hub of In motor cycles,-as heretofore constructed, it involved considerable time and labor to remove the rear traction wheel especially when 'en route, and in case the tire or other a moval of the wheel for effecting proper rebecame necessary. With my improvements presently described in detail, the rear raction wheel can be quickly and conveniently removed for poses without disturbing the other parts of the motor cycle especialliy the driving Wheel and the brake drum, an if necessary, such rear traction wheel can be interchanged with means for detachably con-' the front or sirable.

For the purposes mentioned, the hub 10 of the rear steering wheel if deemed deusual brake mechanism. The hubs 12 and 13 of th brake drum l5 screws the member 19. bearing 17 are mounted shaped bearing members the latter screws on the her 21. The hubs 20 and 23 are secured in the usual manner in the forks 24 and 25 of the motor cycle frame. An axle 26 extends centrally through the hubs 8 memment by the section 36. The latter is provided with against the inner faces of the hers 18 and 21 to hold the same properly likewise the sprocket wheel he sleeve secfitted on the axle 26 and access is had to the spreader 35 by Way of and opening 42 formed in the rim of the hub 10, as plainly indicated in Fig. opening 42 is normally closed by a suitable cover 43. After the sleeve sections 36 and 37 have been adjusted, they are fastened together by a set screw 44 screwing in the head 41 against the boss 40.

The inner face of the hub 12 is provided with a recessed guideway 50, and guideway 51 is formed in the inner face of the hub 13 of the are with slotted extensions 5-1, 55 enga ed by bolts 56, 57 held on the sprocket wheel 14 and the brake drum 15 to securely fasten the hub 10 in central position on the hubs 12 and 13 of the sprocket wheel 14 and the brake drum 15.

In order to insure proper centering of the hub 11) relative to the hubs 12 and 13, use is made of dowels 60 and 61 formed on the lugs 52 and 53 and engaging recesses 62 and 63 formed in the inner faces of the hubs 12 and 13 (see Fig. 1).

When it is desired to remove the traction wheel 11 then the operator unscrews one of the nuts 27 or 28 and pulls the axle 26 out of the hubs 10, 20 and 23. The operator next loosens the nuts 58 and 59 of the bolts 56 and 57 i and slightly presses the sprocket Wheel 14 and the brake drum 15 apart to disengage the dowels (i0 and 61. from their recesses 62 and 63, to allow the operator to slide the lugs 52 and 53 out of the openended guideways and It is understood that the wheel 11 is pulled out from between the sprocket wheel ll and the brake drum 15 in the direction opposite to the one in which the lugs 54, extend, it being understood that on removing the wheel the spreader 35 is carried along but the sprocket wheel 14 and the brake drum 15 remain undisturbed in their usual position. When it is desired to replace the wheel. 11. then the lugs 52 and 53 with their extensions 54, 55 forward are-reengaged with the guidcways 50 and 51 until the centering dowels and 61 sna into the recesses 69 and 63. It will be noticed that When the wheel 11 is replaced, the forked EYiT'B'SlGRE 5i and 55 reiingage the bolts 56 and iii", and. the nuts 58 and 59 are new screwed up to securely fasten the hub 10 in position on the s irocket wheel 14 and the brake drum 15. The axle 26 is now replaced and fastened in position by screwing up the previously removed nut 27 or 28. From the foregoing it'will be seen that the wheel 11 can be quickly removed whenever it is desired to make re airs on the tire or other part, and after sue repairs have been made the wheel can be quickly returned and fastened in place.

In practice it is desirable that the hub of the front or steering Wheel is made the same as the hub 10 of the rear traction wheel 11, that is, that such front wheel hub is rovided with the lugs 52, 53 to permit 0 interchanging the rear or traction wheel with the front or steering wheel whenever it is desired to do so. Thus, for instance, if the tire of the rear traction wheel cannot properly be repaired while en route it may become desirable to exchange such rear trac:

tion wheel with the front steering wheel to permit the user of the motor cycle to safely reach home or a repair shop.

It is understood that when the wheel 11 is in osition the sprocket wheel 14 drives the w eel 11 and the latter drives the brake drum 15. It will also be noticed that by the arrangement described a very firm connection is had between the sprocket Wheel 14, the traction wheel 11 and the brake drum 15 to insure proper running of the motor cycle and to allow proper braking of the same whenever it is desired to do so.

As the brake mechanism is of usual construction it is not deemed necessary to further describe the same. It is also not deemed necessar to describe the motor cycle frame further in detail as the same is of usual construction.
